There is almost no stone sculpture from the 21st Dynasty. Sculpture of the
22nd Dynasty seems to be still very much in the tradition of the late New
Kingdom (about 1550-1069 BC). The 25th and 26th Dynasty is a time of return
to earlier periods for inspiration. Statues are very often modelled on prototypes
of the Old and Middle Kingdom (about 2025-1700 BC). For uninscribed pieces
it is sometimes hard to decide if they belong to the Old or Middle Kingdom
or to the Late Period. UC 14313 is published as belonging to the Old Kingdom
(about 2686-2181 BC) . The inscriptions reveal that the statue belongs to
the Late Period. UC 14642 and UC 16451 are modelled on prototypes of the late
Middle Kingdom. The wig and the 'realistic' face are also typical for that
period (compare the examples given for that period).
The date of UC 16451 is particularly problematic: it was thought to be of
basalt, a favourite Late Period material in sculpture, but closer inspection
reveals that it is of granodiorite, and the late Middle Kingdom parallels
seem so strong that it may well be redated to that period.
